Non-Ozone Depleting R-410A Refrigerant

Owner, Engineer and Contractor BenefitsThe Building Owner/Tenant■ High efficiency units reduce energy consumption/operating costs

and can contribute to earning points toward LEED® certification. ■ Open Choices control feature gives you the flexibility to select

standalone thermostat operation or easy, low cost integration with the BAS of your choice using an add-on communication module.

■ R-410A refrigerant has no ozone depletion potential or phase-out date, helping to minimize environmental impact and protect against refrigerant availability issues over the economic life of your equipment investment.

■ Quiet operation provided by Gentleflo™ cross-tangential fan wheel and quiet rotary compressor with low vibration mass plate design.

■ Double-sloped polymer drain pan and optional closed cell insulation promote superior indoor air quality.

■ Durable construction promotes long life, reliable operation.

The Engineer■ Boiler/tower or geothermal unit selections provide flexibility in

designing the system that best meets the performance and budget requirements of your project.

■ Multiple unit configurations reduce design time and cost.■ Multiple features and options give you the flexibility to select units

that closely match application requirements.

Installing Contractor / Service Personnel■ High sill or low sill design makes it easier to meet space

requirements of new construction and replacement applications.■ Easy access to water connections save time to help reduce installation costs.■ LED status lights on the control box behind the front panel allow

quick troubleshooting.■ Individual left and right end panels provide easy access to the unit

compressor, motor and unit controls with access to the fan section, coil and filter through the front panel.

■ A removable, non-corrosive, double sloped condensate drain pan provides positive condensate removal and is easy to access for service and maintenance.

MicroTech III Unit ControllerThe MicroTech III unit controller is a standalone microprocessor-based control board conveniently located in the unit control box for accessibility. The board is designed to provide standalone control of a Water Source Heat Pump using a wall thermostat or a wall-mounted temperature sensor.

Each unit controller is factory programmed, wired, and tested for complete control of single zone, standalone operation of your McQuay Water Source Heat Pump.

Each unit controller orchestrates the following unit operations:

Enable heating and cooling to maintain setpoint Monitor discharge air temperature based on a room sensor Monitor leaving water temperature Enable fan and compressor operation Relay status of all vital unit functions Monitor all equipment protection controls Support optional control outputs

I/O Expansion ModuleFor added functionality, an optional I/O expansion module interconnects to the MicroTech III unit controller.

Adding an I/O Expansion Module (with an interconnect cable) allows for:

Monitoring of entering water temperature for boilerless electric heat control Outputs for optional electric heat

LonWorks® Communication ModuleThe MicroTech III unit controller can accept a plug-in LonWorks communication module to provide network communications and added functionality to easily integrate with an existing BAS.

The communication module can be factory- or field-installed and is tested with all logic required to monitor and control the unit.

The LonWorks communication module is LonMark 3.4 certified for BAS integration to provide centralized scheduling and management of multiple heat pumps.

An amber, on-board status LED indicates the status of the MicroTech III LonWorks module.

BACnet Communication ModuleThe MicroTech III unit controller can accept a plug-in BACnet communication module to provide network communications and added functionality to easily integrate with an existing BAS. The communication module can be factory- or field-installed and is tested with all logic required to monitor and control the unit.

It is designed to be linked with a centralized building automation system (BAS) through a BACnet communications network for centralized scheduling and management of multiple heat pumps.

Open Loop “Well Water”“Open Loop” well water systems use ground water to remove or add heat to the interior water loop. The key benefit of an open loop system is the constant water temperature, usually 50°F to 60°F, which provides efficient operation at a low first cost. Open Loop applications are commonly used in coastal areas where soil characteristics allow reinjection wells to return the water back to the aquifer. Reinjection wells must be approved by the U.S. Environmental Protection Agency.

Water Source Heat Pump Geothermal Systems

Water source heat pump systems are one of the most efficient systems available for heating and cooling buildings. High efficiency, self-contained McQuay Enfinity units can be placed in virtually any location within a building. Each unit responds only to the heating or cooling load of the individual zone it serves. This provides excellent comfort levels for occupants, better control of energy use for building owners and lower seasonal operating costs.

Boiler/Tower LoopA “Boiler/Tower” application uses a simple two pipe water circulating system that adds heat, removes heat or transfers rejected heat to other units throughout the building. The water temperature for heating is usually provided by a natural gas or electric boiler located in a mechanical room. The condens-ing water temperature is provided by a cool-ing tower that dissipates waste heat. This application can be the lowest cost of the loop options available.

Geothermal Closed LoopVertical loops (shown) are installed by drilling vertical bore holes into the earth and inserting a plastic polyethylene supply/return pipe into the holes. Horizontal loops are installed in trenches approximately 5 feet below the ground surface. Both vertical and horizontal loops extract the Earth’s natural heat and reject it back.

Surface Water or Lake LoopA “Surface Water” or “Lake” (shown) closed loop system is a geothermal loop that is directly installed in a lake or body of water that is near the building. In many cases, the body of water is constructed on the building site to meet run-off or aesthetic require-ments. The size and the depth of the lake is critical, and commercial design services should be used to certify that a given body of water is sufficient for building loads.
